MMS reducing liver function

My friend says that when she was taking MMS her liver function reduced severely. Is that a thing? Have you ever heard of it?

I've not heard of anything like that. I take it regularly and sometimes in pretty high doses and zero problems. I just looked at the testimonials page on liver and everything was very positive. It certainly can't be ruled out but my first guess would be that it's something else causing what she believes to be a liver problem
